Assassin's Creed 3 came out on the PC platform last month, after Ubisoft already released it for the PS3 and Xbox 360 consoles back in October.

Now, the Hidden Secrets Pack, which was released last week for those who got the game's Season Pass, is now available for all owners of Assassin's Creed 3 on the PC.

The add-on brings quite a few new things, so check out its description below, via Steam.

"The Hidden Secrets Pack adds three extra missions, taking you from the Lost Mayan Ruins to the high seas. Every success is rewarded with an in-game weapon! You'll also receive two single-player skins including the original uniform of the Captain of the Aquila and the traditional Colonial Assassin, along with two multiplayer characters including the fearsome Redcoat and the deadly Sharpshooter."
